Comment on "modified quantum-speed-limit bounds for open quantum dynamics in quantum channels"
In a recent paper [Phys. Rev. A 95, 052118 (2017)2469-992610.1103/PhysRevA.95.052118], the authors claim that our criticism, in Phys. Rev. A 94, 052125 (2016)2469-992610.1103/PhysRevA.94.052125, to some quantum speed limit bounds for open quantum dynamics that appeared recently in literature are inv...

| Sumario: | In a recent paper [Phys. Rev. A 95, 052118 (2017)2469-992610.1103/PhysRevA.95.052118], the authors claim that our criticism, in Phys. Rev. A 94, 052125 (2016)2469-992610.1103/PhysRevA.94.052125, to some quantum speed limit bounds for open quantum dynamics that appeared recently in literature are invalid. According to the authors, the problem with our analysis would be generated by an artifact of the finite-precision numerical calculations. We analytically show here that it is not possible to have any inconsistency associated with the numerical precision of calculations. Therefore, our criticism of the quantum speed limit bounds continues to be valid. |
